Su Zi Jiang Qi Tang from the Bureau of Taiyi Prescriptions treats conditions of deficient Yang attacking upward, impaired ascending and descending of Qi, excess in the upper and deficiency in the lower, and copious phlegm-saliva.
Yu Sharen's Jiang Qi Tang treats the same conditions as above.
Hei Xi Dan (Black Lead Pill) treats conditions of copious phlegm-Qi stagnation, excess in the upper and deficiency in the lower, blazing Heart Fire, and depleted Kidney Water.
Ling Sha Dan (Cinnabar and Mercury Pill) treats excess in the upper and deficiency in the lower with copious phlegm-saliva; this medicine is most effective in suppressing and descending (heavy sedation).

Regarding "Ascending and Descending Yin and Yang" (Four prescriptions appear together in this section):
Commentary: The aforementioned prescriptions all gather warm and hot natured medicines, yet the described syndromes are all stated to treat "excess in the upper and deficiency in the lower, with impaired ascending and descending of Qi." What is meant by "excess" is the blazing of Heart Fire; what is meant by "deficiency" is the weakness of Kidney Water. When Fire blazes and Water is weak, there is ascending without descending, causing body fluids to surge and transform into phlegm-saliva, accumulating in the upper. To use mineral and metallic pills, along with damp-heat and aromatic-dry medicines, to tonify the deficiency in the Lower Jiao is like carrying firewood to put out a fire. If one considers it a deficiency of Yang in the Lower Jiao and proposes treatment accordingly, that is also incorrect. If Yang Fire were deficient, then Yin Water would necessarily be abundant, and phlegm-saliva and body fluids would naturally descend with the Qi; why would it be necessary to use such medicines?

Jinkui Shenqi Wan (Kidney Qi Pill from the Golden Cabinet) treats shortness of breath with slight fluid retention; it should be eliminated through urination (Prescription see Tonifying Deficiency Section).
Commentary: Zhang Zhongjing used this prescription to tonify the Kidney and expel water because of Kidney deficiency leading to fluid retention, due to the presence of Ze Xie (Alisma Rhizome) and Fu Ling (Poria) in the formula. Yan Zhihe used this prescription to treat Kidney deficiency-cold failing to control and nourish Kidney Water, causing pathogenic water to overflow upward, resulting in frequent spitting of phlegm-saliva. Since the Kidney is deficient and cold, Yang Fire must be abundant; I wonder what substance is referred to as "controlling and nourishing Kidney Water"? Kidney Water is generated by Tian Yi (the One from Heaven/Primordial Essence), serving as the root of human life; phlegm-saliva is formed from turbid and degenerated body fluids. How can one directly state that Kidney Water fails to control, causing pathogenic water to overflow upward? If it is said that Kidney Water is weak and Yin deficiency makes descent difficult, causing body fluids to degenerate into phlegm-water, thus using this medicine, the rationale becomes clear.

Respectfully noted: Phlegm diseases mostly arise from Dampness, so ancient prescriptions often use medicines such as Nan Xing (Arisaema Cum Bile) and Ban Xia (Pinellia Tuber). However, phlegm disease often involves accompanying pathogens, so medicines vary according to Wind-Cold, Summer-Heat, or Dampness. Furthermore, the human body has distinctions of Upper/Lower and Exterior/Interior; therefore, those in the Exterior are treated with sweating, those in the Interior with purgation, those in the Upper with emesis, and those in the Lower with separation and diuresis. Methods for treating Fluid Retention can be considered quite detailed. Someone asked: Chen Wuzhuo categorized Da Qing Long Tang and Xiao Qing Long Tang, Wu Ling San, and Cheng Qi Tangs as External Causes; Shen Ling Bai Zhu San, Ba Wei Wan, and Shen Su Yin as Internal Causes; Shi Zao Tang, Ting Li Da Zao Xie Fei Tang, Da Ban Xia Tang, Xiao Ban Xia Tang, and Kong Xian Dan as Non-External/Internal Causes. Your compilation of these prescriptions seems to differ in intent. Why? I reply: Da Qing Long Tang and Xiao Qing Long Tang are exterior medicines for External Causes; Wu Ling San and Cheng Qi Tangs are interior medicines for External Causes; Shen Ling Bai Zhu San and Ba Wei Wan are interior medicines for Internal Causes; Shen Su Yin is an exterior medicine for Internal Causes; Shi Zao Tang, Ting Li Da Zao Xie Fei Tang, and Kong Xian Dan are purgative medicines for Non-External/Internal Causes; Da Ban Xia Tang and Xiao Ban Xia Tang are harmonizing medicines for Non-External/Internal Causes. Chen Wuzhuo established his theory based on the Three Causes, so he listed medicines primarily according to etiology, without distinguishing their exterior/interior or internal/external differences. Now, I classify the prescriptions by Exterior/Interior and Internal/External, so it is difficult to strictly adhere to his etiological classification.
